The Pola pendent light addresses the evils of packaging waste. The Styrofoam components that are part of its structure are also used as the packaging material. Like 97% Soap, Pola would not be possible with hot incandescent light bulbs.

I really liked 100% Plastic for its dual purpose: It both highlights the extreme wastefulness of manufacturing and provides a solution.

All of the injected material used during production of the polystyrene self-assembly 100% Plastic was used to make the lamp. No manufacturing waste can only be obtained with extreme maximization of material use.

Inspired by the massive amount of plastic found on a factory floor after a day's work, the Poly lamp is made of post-industrial Polyethylene.

Perhaps it also symbolizes the multiple layers that need to be approached and integrated to truly make any positive global change.
